Considering a Pearson 323
The Pearson 323 that I was familar with had a wooden post that went from the mast step on the deck to somewhere on the cabin sole or keel. It was not a keel stepped mast.
I have a survey from publication called "Independent Yacht Survey" That makes a comment on the hull to deck fastening.
Like most things if it''s done right it''s ok.
In my opinion very few boats are offshore boats. And fewer sailors. This includes me.
Although I will be offshore this winter again on a 900'' boat.
I like the Pearson 323. Not enough to buy one but they are ok.
